(Cl. 16137) This invention relates to a door stop, and more particularly, to a door stop adapted for use with hinges in which the leaves pivot about a removable bolt or pintle. Priorly, numerous forms of door stops have been employed. For example, a door stop for use with a pintleleaf type hinge is disclosed in Civitelli, United States Patent 2,813,293 issued Nov. 19, 1957. Another type of door stop is disclosed in Kroehling, Patent 1,616,265 issued Feb. 1, 1927. A type of door stop is disclosed in Madsen, Patent 2,280,655 issued Apr. 21, 1942. Still another type of door stop or door check is disclosed in Allen Patent 2,592,230, issued Apr. 8, 1952. The Civitelli, Madsen and Allen structures are all employed on the outside of the hinge to limit the outward or opening movement of a door. The Kroehling structure is designed to limit the closing movement of a door, i.e., to prevent the door from closing. The above mentioned structures exhibit numerous disadvantages. For example, they are relatively eX- pensive to manufacture and limited in application to controlling door movement in a single direction. Further, certain of these structures are not provided with features which provide for flexibility of application which would permit them to be readily converted to control the opp'osite direction of door movement.

Accordingly, it is an object of .this invention 'to provide a novel door stop which eliminates the above-enumerated disadvantages.

Another object of this invention is to provide a door stop or door check which can be quickly modified to control either the opening or the closing movement of a door.

It is another object of this invention to provide an improved door stop which may be mounted on the bolt 0r pintle of a hinge comprising a pair of leaves and may be, quickly moved from a position between the door and the jamb to a position eXteriorally of the door and the jamb without removing the bolt or pintle to thereby be made to control the opening movement of the door or may, alternatively, be employed to limit the closing movement of the door.

I Still another object of this invention is to provide a door stop which can be manually moved from a position between the door and the door jamb on the leaf side of the hinge to a position exteriorally of the door and the jamb to thereby control the outward movement of the door.

It is still a further object of this invention to provide a novel door stop which can be quickly and easily moved from positions of operability to a position of inoperability either between the door and jamb or between the door anddoor facing.

Briefly, in accordance with aspects of this invention, I provide, in one illustrative embodiment, a door stop device including a collar or sleeve for encircling the hinge pin, bolt, or pintle of the hinge, which hinge is comprised of a pair of hinge leaves which swing about the bolt or pintle, and an elongated member connected intermediate its length to the collar for longitudinal rotation relative to the collar so that the elongated member may be rotated from a position in which a pair of angularly disposed end surfaces engage the door and jamb to a position in which a pair of sides engage the door and jamb. The device may also be moved across the hinge to engage the door and facing to limit the opening movement of the door. In this illustrative embodiment, the elongated member is preferably formed of resilient material such as plastic or rubber and is connected to the collar member by a reduced neck portion. The neck portion comprises a swivel connection in the form of a pair of wires having in-turned portions which project into suitable diametrically opposed apertures in the collar or sleeve so that the elongated member of the door check or door stop may be rotated into the plane containing the pintle and passed over the pintle, bolt, or hinge pin from a position between the door jamb and the door to a position between the door and the door facing. Advantageously, this illustrative embodiment of swivel connection includes spring means on the pair of wires to force the elongated member away from the collar or sleeve and the pair of wires terminate in a pair of oppositely directed pin portions which engage a pair of aligned recesses in the outer surface of the elongated member to prevent relative rotation between the elongated member and the swivel connection. Also advantageously, a second pair of aligned recesses is provided at an agle of relative to the first pair of recesses so :that the elongated member may be moved to compress the spring means and rotated 90 and released so that the hinge pin or pintle and the elongated member are contained in a common vertical plane. The door stop. may now be rotated over the pin-tle to a position exteriorally of the door and the door facing. When the elongated member is exteriorally of the door and the door facing, it may again be rotated by forcing the elongated member to compress the spring means and then released so that the pin portions engage the 90 recesses such that the angularly disposed end surfaces of the elongated member will engage the door and facing to limit the outward movement of the door.

In accordance with a preferred embodiment of this invention, I provide a door stop which is of unitary construction and formed of a plastic, or resilient, material. Advantageously, this door stop includes a collar portion for receiving the bolt or pintle of the hinge, a reduced neck portion, and an elongated portion connected to the reduced portion such that the elongated portion may be rotated at least 90 relative to the collar portion by twisting the reduced portion. Preferably, the elongated portion terminates in a pair of angularly disposed surfaces which may advantageously be of an angle of 90 or any other angle which is to be maintained between the door and jamb or door and facing. The device may be installed by manually removing the bolt or pintle and passing the bolt or pintle through the collar and reinserting the bolt or pintle into the cylindrical portion of the hinge leaves. After the door check or door stop is installed, it may be manually moved from a position between the door jamb and the door to a position between the door facing and the door by twisting the elongated reduced :portion by applying a force to the elongated member and passing the elongated member between the door and the door j-amb. After the elongated portion is passed between the door and the jamb, it may again be rotated into a plane perpendicular to the bolt where the elongated portion will limit the opening movement of the door. The simplicity of the plastic embodiment and the unitary construction make it adaptable to be either molded or extruded. Because it is of a non-metallic construction, it is relatively inexpensive. Further, because of this nonmetallic resilient material, it cannot damageeither the door, the door facing, or the door jamb.

These and various other objects andfeatures of the invention will be more clearly understood from a reading of the detailed description of the invention in conjunction with the drawing in which:

FIGURE 1 is a view in perspective of one illustrative embodiment of this invention installed on a door hinge of the pintle-leaf type;

FIGURE 2 is a plan view of the embodiment of FIG- URE 1 taken along the line 2-2 thereof and looking in the direction of the arrows;

FIGURE 3 is a view in perspective of the embodiment of FIGURE 1 showing the door stop in a position rotated 90 relative to the position of FIGURES 1 and 2;

FIGURE 4 is a view in elevation, taken along the line 4-4 of FIGURE 3, and looking in the direction of the arrows;

FIGURE 5 is a perspective view of another illustrative embodiment of this invention;

FIGURE 6 is a detail of the embodiment of FIGURE 5; and

FIGURE 7 is a side view of the embodiment of FIG- URE 5 taken along the line 7-7 thereof and looking in the direction of the arrows.

FIGURE 1 is a view in perspective of a door jamb 10 about which is pivotally mounted a door 12 by means of a hinge 14. The hinge 14 includes a pair of leaves 15, 16. The leaf 15 is secured to the door jamb It by suitable means such as by screws 17 and the leaf 16 is secured to the door 12 by suitable means such as by screws 18. The binge leaves 15, 16 include cylindrical portions 19, 20 which are connected together by a hinge pin, bolt or pintle 21. As shown in FIGURE 1, the door is held open by means of a novel door stop 22 which includes an elongated resilient member 23 connected to a suitable collar 24 on the bolt 21 by means of a swivel type connecting link 25. Preferably, the elongated member 23 terminates in a pair of angularly disposed sides 27, 28 which, in this particular instance, are positioned at an angle of 90 relative to each other. The outer surface of the member 23 is a relatively fiat surface 29 having two pairs of opposed notches 30, 31 therein. Advantageously, these notches are formed at 90 relative to each other to act as a locking socket for the connecting link in a manner which will be subsequently described.

FIGURE 2 is a plan view of the embodiment of FIG- URE 1, taken along the line 2-2 and looking in the direction of the arrows. FIGURE 2 shows in solid lines the device in the position shown in. FIGURE 1 and shows in dotted lines the position to which the door stop 22 may be moved in order to control the opening movement of the door 12. As shown in solid lines, the elongated resilient member 23 lies in a substantially horizontal plane and is retained in this plane by means of the linking means 25. This linking means includes a pair of identically formed wire members 33, 34 which has a pair of opposed inwardly projecting end portions 35, 36 which engage suitable apertures in the collar 24. The connecting wire members 33, 34 include a pair of parallel sections 38, 39 which are in contact with each other and which terminate in a pair of oppositely directed pin portions 40, 41. These projections 40, 41 rest in the pair of opposed aligned notches 31 in the surface 29 of the elongated resilient member 23. The elongated member 23 is pushed outwardly from the pin 21 by means of a helical spring 44 which is in a recessed or notched portion 45 of the elongated member 23 and encircles the parallel sec-' tions 38, 39 of the wire members 33, 34. If it is desired to rotate the elongated member 23 longitudinally relative to the parallel sections 38, 39 to cause the elongated member 23 to lie in a vertical plane, the door 12 is rotated outwardly away from the door jamb 10 and the member 23 is first pushed toward the pin 21 such that the elongated projections 40, 41 extend beyond the notches 31. The elongated member is now rotated into a vertical plane, as shown'in FIGURE 3, and released. The outward projections 40, 41 will now be forced into the pair of recesses 30,-which recesses are perpendicular to the recesses 31.

FIGURE 4 is a view in elevation, partly in section, of

the embodiment of FIGURE 3 taken along the line 4-4 thereof. In this position, the door 12 may be rotated toward the jamb 10 until the door 12 engages the elongated substantially fiat surface 26 of the door stop 22. By emplOying the stop 22 in this position, the door maybe permitted to be stopped just before the door reaches a closed position. FIGURE 4 also shows, in dotted line, the door stop 22 rotated in a position on the outside of the hinge 14. Thus, the door stop 22, in the dotted line position, will limit the outward movement of the door 12 relative to the door facing by the extent of the thickness of the elongated member 23. If, however, the elongated member is noW rotated into a plane substantially perpendicular to the bolt axis, as indicated in dotted outline in FIGURE 2, then the elongated portion 23 will limit the outward movement of the door 12 until the door reaches a position of approximately relative to the door facing 49.

Referring now to FIGURE 5, there is shown a view in perspective of a door in which a unitary, resilient preferred embodiment 48 of this invention is employed to retain the door in its open position. In this view, the door 12 is supported relative to the door jamb 10 by means of the hinge 14 and the hinge pin 21 is inserted into the cylindrical portions 19, 20 of leaves 15, 16 through a collar 50 of the unitary resilient door stop 48. The collar 50 is connected to an elongated section or portion 52 by means of a reduced section or neck portion 54. As shown in FIG- URE 6, the unitary door stop 48 has a pair of substantially perpendicular edges 56, 57 which surfaces engage the door 12 and the jamb 10, respectively. If it is desired to employ the door stop 48 to limit the outward movement of the door 12 relative to the jamb 10, the elongated portion 52 is manually gripped and rotated to twist the neck portion 54 and the elongated portion 52 is pushed between the door 12 and the jamb 10 until it can be reached from the outside of the door 12 and pulled into a positionsuc-h that the elongated portion 52 again lies in a substantially perpendicular plane relative to the bolt axis, as viewed in FIGURE 5, such that the surface 56, of FIGURE6, will engage the outer surface of the door facing and the surface 57 will engage the outer surface of the door 12. Further, this position will permit the door 12 to be completely closed against the jamb 10. FIGURE 7 is a side elevational view of the novel door stop of FIGURE 6 taken along the line 7-7 thereof and looking in the direction of the arrows. This view shows that the elongated portion 52 has a pair of substantially parallel sides 58, 59.

While I have shown and described two illustrative embodiments of this invention, it isunderstood that the concepts thereof may be employed in other embodiments without departing from the spirit and scope of this invention. From the foregoing explanation, it is understood that t-hese two embodiments can be quickly and economically formed and manually installed and manually changed from a position to control the opening movement of the door to a position to control the closing movement of the door without the use of any tools.
